Background: Identification of pancreatic cancer (PC) local invasion is crucial to optimize patients' selection for surgery.
Aims: To determine the diagnostic accuracy of contrast-enhanced computed tomography (CECT) and endoscopic ultrasound (EUS) in local staging of PC.
Methods: We performed a multicenter study including all patients with PC who underwent surgery.
Results: One hundred twelve patients were included. Surgical findings of peri-pancreatic lymph nodes (LN), vascular and adjacent organ involvement were seen in 67 (59.8%), 33 (29.5%) and 19 patients (17%), respectively. The diagnostic performance of EUS was better than CECT in peri-pancreatic LN. The sensitivity, specificity, positive predictive value (PPV) and negative predictive (NPV) of CECT vs. EUS were 28.4%, 80%, 67.9% and 42.9% vs. 70.2%, 75.6%, 81% and 63%, respectively. For vascular and adjacent organ involvement, the sensitivity, specificity, PPV and NPV were 45.5%, 93.7%, 75%, 80.4% and 31.6%, 89.2%, 37.5% and 86.5% for CECT, respectively, vs. 63.6%, 93.7%, 80.8%, 86.1% and 36.8%, 94.6%, 58.3% and 88% for EUS, respectively. Combining both CECT and EUS, the sensitivity for peri-pancreatic LN, vascular and adjacent organ involvement improved (76.1%, 78.8% and 42%), respectively.
Conclusion: EUS was superior to CECT in local staging. Combined EUS and CECT had a higher sensitivity than either alone.

Functional high risk multiple myeloma (FHRMM) remains a challenging entity with poor outcomes and limited survival, and there is no international consensus on optimal second-line therapeutic strategies in relapsed/refractory patients. In this multicenter real-world retrospective study, we investigated clinical characteristics and outcomes of a total of 62 FHRMM patients previously treated with a first-line daratumumab-based quadruplet regimen or who relapsed within 12 months after frontline autologous stem cell transplantation (ASCT). In our cohort, the overall response rate was 61%, with 42% of patients achieving a very good partial response (VGPR) or better.

Small-cell lung cancer (SCLC), an aggressive neuroendocrine tumor strongly associated with exposure to tobacco carcinogens, is characterized by early dissemination and dismal prognosis with a five-year overall survival of less than 7%. High-frequency gain-of-function mutations in oncogenes are rarely reported, and intratumor heterogeneity (ITH) remains to be determined in SCLC. Here, via multiomics analyses of 314 SCLCs, we found that the ASCL1/MKI67 and ASCL1/CRIP2 clusters accounted for 74.

Deep learning approaches have improved disease diagnosis efficiency. However, AI-based decision systems lack sufficient transparency and interpretability. This study aims to enhance the explainability and training performance of deep learning models using explainable artificial intelligence (XAI) techniques for brain tumor detection.

Omega loop C (residues 40-57) of cytochrome c (Cytc) is a common location for naturally-occurring variants of human Cytc that cause thrombocytopenia 4 (THC4). These variants are characterized by significant increases in the intrinsic peroxidase activity of Cytc, which appears to be linked to increased dynamics in Ω-loop D (residues 71-85). The mutations in Ω-loop C enhance the dynamics of Ω-loop D by decreasing the acid dissociation constant of the trigger group (pK) of the alkaline conformational transition.

Prior researches on global-local processing have focused on hierarchical objects in the visual modality, while the real-world involves multisensory interactions. The present study investigated whether the simultaneous presentation of auditory stimuli influences the recognition of visually hierarchical objects. We added four types of auditory stimuli to the traditional visual hierarchical letters paradigm:no sound (visual-only), a pure tone, a spoken letter that was congruent with the required response (response-congruent), or a spoken letter that was incongruent with it (response-incongruent).
